I have a broadcast only conference room setup where all users who dial in get audio / video, but can't send it. I would like to play a video file to it, but when I try it I only get audio.
conference 4600 play /root/spacex.mp4
I can broadcast to a specific user and get audio and video:
uuid_broadcast 9f857c4a-0294-4446-8864-e92a8ac0433c /root/spacex.mp4
